Stacy Bannerman didn't recognize her husband after he returned from his second tour in Iraq.

"The man I had married was not the man that came back from war," she says.

Bannerman's husband, a former National Guardsman, had been in combat and been diagnosed with post-traumatic stress disorder. He behaved in ways she had never expected, and one day, he tried to strangle her.

"I had been with this man for 11 years at that point, and there had never been anything like this before," Bannerman said. "I was so furious and so afraid."

Pasang Lama is one of the survivors of the 2015 earthquake in Nepal that took 9,000 lives across the country, including his parents, brother and more than 30 relatives from his home village in the Langtang Valley. To cope with his loss, the 24-year-old has turned to an unexpected hobby: photography.

"After the earthquake, we lost everything, even the culture," Lama says. He and other young survivors from Langtang have started photographing their lives post-disaster.
